Cardiovascular Consequences of Repetitive Arousals over the Entire Sleep Duration

Figure 2

Typical waveform of DVP over a single cardiac cycle. It is derived from a set of real data of the present study. Point A indicates the first peak which is generated by the contraction of left ventricle. Point B is the inflection point which is formed largely by the reflection of pressure from the arteries in the lower extremities back up to the aorta. The time difference between these two points is defined as .
